, x (is a member of) [0,10]
I started off by doing this
2x+1>e^(3cos(x))
dont know how to proceed.
What exactly is the question? Solving the given inequality? What were the instructions? It cannot be solved by hand. You are obviously expected to use technology such as a graphics calculator to draw the graphs of y = ln(2x + 1) and y = 3cos(x) and then get an approximate solution.
